### TL;DR

Closes Shopify/oasis-frontend#524

Added SERIALIZABLE transaction isolation level to have a clear error if multiple backfills are happening at the same time.

### What changed?

Modified the `migrate_db` function to set the transaction isolation level to SERIALIZABLE when running annotation backfills. This ensures that if multiple backfill operations attempt to run simultaneously, a transaction error will be thrown to prevent conflicts.

### How to test?

1. Run database migration with annotation backfills enabled
2. Attempt to run multiple concurrent migrations to verify that transaction errors are properly thrown
3. Verify that single migration runs complete successfully without issues

### Why make this change?

Previously, during a backfill there was a `Duplicate KEY error` which was ambiguous why this error occurred.  Adding this isolation level will give better troubleshooting message what's happening if multiple backfills are happening.
